'''Photosynthesis''' is a biological process in which organisms such as plants, algae, and certain bacteria convert light energy into chemical energy, producing organic compounds and releasing oxygen.

== Remembering (Knowledge / Recall) 🧠 ==
Foundational terms, components, and basic facts.

=== Core terminology & definitions ===
* '''[https://wikipedia.org/wiki/Photosynthesis Photosynthesis]''' — Light-driven synthesis of carbohydrates from carbon dioxide and water.
* '''[https://wikipedia.org/wiki/Chlorophyll Chlorophyll]''' — Light-absorbing pigment central to capturing solar energy.
* '''[https://wikipedia.org/wiki/Chloroplast Chloroplast]''' — Organelle where photosynthesis occurs in plants and algae.
* '''ATP / NADPH''' — Molecules generated during light reactions and used in carbon fixation.

=== Key components / actors / elements ===
* '''Thylakoids''' — Membranous structures hosting light-dependent reactions.
* '''Stroma''' — Fluid compartment where the Calvin cycle operates.
* '''Photosystems I & II''' — Protein–pigment complexes absorbing photons and driving electron flow.
* '''Reactants & products''' — CO₂, H₂O → glucose, O₂.

=== Canonical models, tools, or artifacts ===
* '''[https://wikipedia.org/wiki/Calvin_cycle Calvin cycle]''' — Pathway converting CO₂ into sugars.
* '''[https://wikipedia.org/wiki/Z-scheme Z-scheme]''' — Model of electron transport in light reactions.
* '''[https://wikipedia.org/wiki/Light-dependent_reactions Light-dependent reactions]''' — Photochemical phase generating ATP and NADPH.

=== Typical recall-level facts ===
* Occurs in plants, algae, and some bacteria (e.g., cyanobacteria).
* Fundamental to Earth’s oxygen supply.
* Converts solar energy into chemical energy via pigments.

----

== Understanding (Comprehension) 📖 ==
Conceptual relationships and explanatory context.

=== Conceptual relationships & contrasts ===
* Complements '''[https://wikipedia.org/wiki/Cellular_respiration cellular respiration]''', reversing its inputs and outputs.
* Key component of global '''carbon cycles''' and climate regulation.
* Distinct from '''chemosynthesis''', which uses chemical rather than light energy.

=== Core principles & paradigms ===
* Dependent on photon absorption and electron excitation.
* Separation of energy capture (light reactions) from carbon fixation (Calvin cycle).
* Relies on proton gradients for ATP synthesis via ATP synthase.

=== How it works (high-level) ===
* '''Inputs''' — Light, CO₂, water.
* '''Processes''' — Light absorption → electron transport → ATP/NADPH production → carbon fixation.
* '''Outputs''' — Carbohydrates (e.g., glucose) and oxygen.

=== Roles & perspectives ===
* '''Plants''' — Use photosynthesis for energy and growth.
* '''Ecosystems''' — Primary productivity supporting food webs.
* '''Global systems''' — Major driver of atmospheric O₂ and CO₂ levels.

=== Core task loops / workflows ===
* Measuring photosynthetic rate via oxygen production or CO₂ uptake.
* Adjusting light, water, and nutrient variables in plant growth experiments.
* Culturing algae under controlled lighting for biomass studies.

* Quantum efficiency (ratio of photons absorbed to electrons transported).
* Net primary productivity metrics.
* Water-use efficiency and light-use efficiency analyses.

=== Maturity & adoption models ===
* Agricultural and ecological applications well established.
* Synthetic-biology adaptations emerging but experimental.
* Increasing role in carbon sequestration strategies.
